Bullet



B. G. CHILDS BULLET Filed May 1, 1955 I nventm Ato'mey B. a. Chiid'sPatented June 30, 1936 UNlTED STATES PATENT OFFICE 3 Claims.

This invention relates to a bullet, the general object of the inventionbeing to provide a streamline bullet so formed as to reduce vacuum dragand air resistance which results in a flattened trajectory and increasesaccuracy in shooting.

Another object of the invention is to provide fins on the rear part ofthe bullet which conform to the spiral grooves in the gun or rifle andalso to provide means whereby the exploding gases will act with fullforce upon the bullet throughout the length of the barrel.

This invention also consists in certain other features of constructionand in the combination and arrangement of several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:-

Figure 1 is a sectional view of a shell containing the bullet, thebullet being shown in elevation.

Figure 2 is a longitudinal sectional view through the bullet.

Figure 3 is a view looking toward the rear end of the bullet.

Figure 4 is a longitudinal sectional view through another form of thebullet.

Figure 5 is a view of the wadding.

As shown in these views the bullet A is formed of a substantiallycylindrical intermediate part, a pointed front end and a pointed rearend, said rear end having the substantially spiral fins I thereon whichconform to the spiral grooves in the gun barrel, the fins terminating anappreciable distance from the rear end of the bullet so that this rearend forms a pointed tail as shown. The rear ends of the fins formshoulders for receiving the front end of the wadding device showngenerally at B in Figure 5. This device includes a casing 2 preferablyof metal which encloses the disks 3 of any suitable material, the devicehaving a tapered opening 4 therein for receiving the tail of the bullet.Asshown in Figure 1 the wadding device encloses the tail end of thebullet when placed in a shell C with the open end of the shell reducedto fit around the intermediate part of the bullet and the wadding, thebullet being provided with a groove 5 into which the end of the shell iscrimped in the usual manner. Thus when the powder in the shell isignited the resulting gases will act on the wadding and propel thebullet through the barrel of the gun, the wadding and the outer jacketentering the grooves in the barrel preventing the escape of the gasesthrough the grooves so that the full force of these gases will act uponthe bullet. As soon as the bullet leaves the barrel the wadding willdrop therefrom.

Figure 2 shows the body of the bullet formed of any suitable materialwith a jacket of steel or the like, shown at 6 fitting over the rearpart of the body, this jacket carrying the fins l and the tail and thebody is grooved as at 1 and 8 for receiving parts of said jacket whichare pressed into said grooves. Another jacket 9 fits over the front ofthe body and over the front part of the jacket 6 and the rear portion ofthe jacket 9 is grooved as shown at It] to press part of the jacket intothe grooves of the jacket 5 where the said jacket is pressed into thegroove 8 and this groove I receives the crimped end of the shell at 5.

Figure 4 shows the body I I formed of any suitable material shaped toprovide the fins and tail with the pointed front end l2 of the bulletformed of lead which has a portion l3 entering a socket M formed in thebody II. The jacket IS in this form of bullet terminates short of thepointed end of the part I2 and is pressed in the said part I2 as shownat It and the rear end of the jacket I is flanged as at I! and enters agroove in the body II. The fins shown at I are formed on the body I land the tail I8 is also formed on the body and is provided with theprojections l9 engaging the wadding to hold the wad on the tail untilthe bullet leaves the barrel.

As before stated this invention provides means whereby the full force ofthe gases will act ta project the bullet from the barrel without loss ofgases and vacuum drag and resistance are reduced to minimum. As will beseen the fins serve two purposes, one to give a solid backing for thegases by way of the wadding that transmits the energy of the gases tothe bullet through the fin ends, the other purpose being to impart aspinning motion to the bullet through its course of flight which resultsin more accurate shooting especially at long ranges.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andarrangement of the several parts, provided that such changes fall withinthe scope of the appended claims.

What is claimed is:-

1. A bullet of the class described comprising a body part having asubstantially cylindrical intermediate portion and pointed front andrear ends, a jacket enclosing the intermediate and rear parts of thebullet and having fins thereon of spiral formation, the rear ends ofwhich are straight to form shoulders and terminate an appreciabledistance from the rear end of the jacket, the intermediate part of thebody having an annular groove therein, a jacket enclosing the front ofthe body overlapping the front portion of the first-mentioned jacket,said jacket having portions pressed into the grooves, the pressedportion of the second jacket forming a groove for receiving a portion ofa shell.

2. A bullet of the class described comprising a body having spiral finson its rear portion which terminate in straight ends located anappreciable distance from the rear end of the body, said rear end beingpointed, a head forming portion attached to the body and being pointedand a jacket enclosing the intermediate portion of the body and aportion of the head forming portion, the front end of the jacketterminating short of the point of the head forming portion and beingpressed into the same, the rear end of the jacket being flanged andextending into the body.

3. A bullet of the class described comprising a body part having 'asubstantially cylindrical intermediate portion and pointed front andrear ends, and a jacket enclosing the intermediate and rearcparts of thebullet and having fins thereon of spiral formation, the rear ends ofwhich are straight to form shoulders and terminate an appreciabledistance from the rear end of the jacket.
